Answer:
r = 0.16
Step-by-step explanation:
C = 2·π·r
1 = 2·π·r
1/2 = π·r
0.5 = π·r
0.5 / 3.14 = r
0.16 = r
Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute
So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.
So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.
Which would get us: Mrs. Dean: 150 wpm
Mr. Kovacs: 96(1.25)=120wpm
Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.
